An electrical network is an interconnection of electrical components or a model of such an interconnection, consisting of electrical elements. An electrical circuit is a network consisting of a closed loop, giving a return path for the current. Linear electrical networks, a special type consisting only of sources, linear lumped elements, and linear distributed elements, have the property that signals are linearly superimposable. They are thus more easily analyzed, using powerful frequency domain methods such as Laplace transforms, to determine DC response, AC response, and transient response.
Electronics comprises the physics, engineering, technology and applications that deal with the emission, flow and control of electrons in vacuum and matter. It uses active devices to control electron flow by amplification and rectification, which distinguishes it from classical electrical engineering which uses passive effects such as resistance, capacitance and inductance to control current flow.
An integrated circuit or monolithic integrated circuit is a set of electronic circuits on one small flat piece of semiconductor material, usually silicon. Large numbers of tiny MOSFETs integrate into a small chip. This results in circuits that are orders of magnitude smaller, faster, and less expensive than those constructed of discrete electronic components. The IC's mass production capability, reliability, and building-block approach to integrated circuit design has ensured the rapid adoption of standardized ICs in place of designs using discrete transistors. ICs are now used in virtually all electronic equipment and have revolutionized the world of electronics. Computers, mobile phones, and other digital home appliances are now inextricable parts of the structure of modern societies, made possible by the small size and low cost of ICs.
Circuit switching is a method of implementing a telecommunications network in which two network nodes establish a dedicated communications channel (circuit) through the network before the nodes may communicate. The circuit guarantees the full bandwidth of the channel and remains connected for the duration of the communication session. The circuit functions as if the nodes were physically connected as with an electrical circuit. Circuit switching originated in analog telephone networks where the network created a dedicated circuit between two telephones for the duration of a telephone call. It contrasts with message switching and packet switching used in modern digital networks in which the trunklines between switching centers carry data between many different nodes in the form of data packets without dedicated circuits.
Direct current (DC) is the one directional flow of electric charge. An electrochemical cell is a prime example of DC power. Direct current may flow through a conductor such as a wire, but can also flow through semiconductors, insulators, or even through a vacuum as in electron or ion beams. The electric current flows in a constant direction, distinguishing it from alternating current (AC). A term formerly used for this type of current was galvanic current.
The Circuit Paul Ricard is a French motorsport race track built in 1969 at Le Castellet, Var, near Marseille, with finance from pastis magnate Paul Ricard. Ricard wanted to experience the challenge of building a racetrack. The circuit has hosted the FIA Formula One French Grand Prix since 2018, having previously hosted it intermittently from 1971 to 1983, and every year from 1985 to 1990.
A printed circuit board (PCB) mechanically supports and electrically connects electrical or electronic components using conductive tracks, pads and other features etched from one or more sheet layers of copper laminated onto and/or between sheet layers of a non-conductive substrate. Components are generally soldered onto the PCB to both electrically connect and mechanically fasten them to it.
The United States courts of appeals or circuit courts are the intermediate appellate courts of the United States federal judiciary. The courts are divided into 13 circuits, and each hears appeals from the district courts within its borders, or in some instances from other designated federal courts and administrative agencies. Appeals from the circuit courts are taken to the Supreme Court of the United States. The district, appellate, and Supreme courts are all authorized under Article Three of the United States Constitution.
A short circuit is an electrical circuit that allows a current to travel along an unintended path with no or very low electrical impedance. This results in an excessive current flowing through the circuit. The opposite of a short circuit is an "open circuit", which is an infinite resistance between two nodes.
A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit. Its basic function is to interrupt current flow after a fault is detected. Unlike a fuse, which operates once and then must be replaced, a circuit breaker can be reset to resume normal operation.
The United States Court of Appeals for the Ninth Circuit is a federal court of appeals that has appellate jurisdiction over the district courts in the following districts:
The United States Court of Appeals for the Second Circuit is one of the thirteen United States Courts of Appeals. Its territory comprises the states of Connecticut, New York, and Vermont. The court has appellate jurisdiction over the district courts in the following districts:
The United States Court of Appeals for the Fifth Circuit is a federal court with appellate jurisdiction over the district courts in the following federal judicial districts:
The United States Court of Appeals for the District of Columbia Circuit is one of the thirteen United States Courts of Appeals. It has the smallest geographical jurisdiction of any of the U.S. federal appellate courts, and covers only one district court: the U.S. District Court for the District of Columbia. It meets at the E. Barrett Prettyman United States Courthouse, near Judiciary Square, Washington, D.C.
The Circuit de Barcelona-Catalunya is a motorsport race track in Montmeló, Catalonia, Spain. With long straights and a variety of corners, the Circuit de Barcelona-Catalunya is seen as an all-rounder circuit. The track has stands with a capacity of 140,700. The circuit has FIA Grade 1 license.
Circuit de Monaco is a street circuit laid out on the city streets of Monte Carlo and La Condamine around the harbour of the principality of Monaco. It is commonly referred to as "Monte Carlo" because it is largely inside the Monte Carlo neighbourhood of Monaco.
The Circuit de Spa-Francorchamps is a motor-racing circuit located in Stavelot, Belgium. It is the current venue of the Formula One Belgian Grand Prix, hosting its first Grand Prix in 1925, and has held a Grand Prix every year since 1985.
The Red Bull Ring is a motorsport race track in Spielberg, Styria, Austria.
The Circuit des 24 Heures du Mans, also known as Circuit de la Sarthe located in Le Mans, Sarthe, France, is a semi-permanent motorsport race course, chiefly known as the venue for the 24 Hours of Le Mans auto race. Comprising private, race-specific sections of track in addition to public roads which remain accessible most of the year, its present configuration is 13.626 kilometres (8.467 mi) long, making it one of the longest circuits in the world. The capacity of the race stadium, where the short Bugatti Circuit is situated, is 100,000. The Musée des 24 Heures du Mans is a motorsport museum located at the main entrance of the venue.
Circuit of the Americas (COTA) is a Grade 1 FIA-specification 3.426-mile (5.514 km) motor racing track and facilities located within the extraterritorial jurisdiction of Austin, Texas. The facility is home to the Formula One United States Grand Prix, the IndyCar Classic, and the Motorcycle Grand Prix of the Americas, a round of the FIM Road Racing World Championship, as well a round of the Americas Rallycross Championship. It previously hosted the Australian V8 Supercars, the American Le Mans Series, the Rolex Sports Car Series, the FIA World Endurance Championship, and the IMSA WeatherTech SportsCar Championship. NASCAR will begin racing at the circuit in 2021.
